Title: Manufacture of activated carbon
Inventor: FUJIMAGARI HITOSHI
IPC: C01B31/12
Filed: 1984-01-31
Abstract: PURPOSE:To manufacture economically activated carbon having excellent performance by impregnating an activator into the activated carbon material having water-repellent surfaces in a state which said material is finely crushed, and performing heat treatment to carbonize and activate said impregnated material. CONSTITUTION:Activated carbon materials having the water-repellent surfaces, for example, the shells of peanut which are scrapped or used only as fuel presently are crushed to <=1,000mu, preferably <=500mu. An activator, for example, an aqueous zinc chloride soln. is added to the crushed materials and the mixture is stirred for about 1hr while maintaining it at 90-95 deg.C to impregnate the zinc chloride. Then, the mixture is filtered and dried and subjected to heat treatment at >=500 deg.C to carbonize and activate the impregnated materials.

Title: Semiconductor substrate etching device
Inventor: YOSHIKAWA KIYOSHI
IPC: H01L21/68
Filed: 1991-01-16
Abstract: PURPOSE:To efficiently perform an etching process only on the end face of a substrate in a short time by bringing the end face of the substrate into contact with an etching liquid fed into the groove section of a grooved roller. CONSTITUTION:A substrate 13 is positioned so that the end face of the substrate 15 can get into a groove section 21c on the side face of a grooved roller 21a in a non-contact state. The groove section 21c of the roller 21a is fed with an etching liquid 25 from an etching liquid feeding nozzle 22a and the liquid 25 is held in the groove section 21 by surface tension. Since the end face of the substrate 15 is always wetted with fresh liquid 25 as the roller 21a and substrate 15 rotate, a uniform and efficient etching process can be performed only on the end face and, since the need of such processes as applying and removing an etching resisting liquid to and from the surface of the substrate except the end face, the process can be shortened and the yield can be improved sharply.

Title: Optical disk recording and reproducing device
Inventor: WAKAMI NOBORU
IPC: G11B7/004
Filed: 1986-01-28
Abstract: PURPOSE:To improve a BER (bit error rate) by setting the threshold of a read circuit of a reproduced signal in read after write (RAW) state in accordance with the polarity of a means which detects foreign matters and defects in a disc base material and on tracks. CONSTITUTION:Taking notice of the fact that the polarity of the amplitude is probably dropped out to the minus side by the influence of foreign matters of a disk, the detection level of the reproduced signal is set to a position [level (b)] higher than the position of a half of the amplitude. Thus, a detected read signal cannot be read in the RAW state if drop-out of the amplitude for foreign matters of the disc is on the boundary. A level setting circuit 3 sets the detec tion level to the position higher than the position of a half of the amplitude of the reproduced signal, to which the detection level is set for normal repro duced signal read, in the RAW state in accordance with the output of a RAW state discriminating circuit 2. A comparing circuit 4 compares the reproduced signal with the detection level set by the circuit 3.

Title: Optical system
Inventor: GOTOU TOSHIHIKO
IPC: G11B7/1359
Filed: 1983-02-04
Abstract: PURPOSE:To obtain a collimating means of a semiconductor laser whose longitudinal and lateral widths are made equal by making a beam having a slender section made incident from the base of an isosceles triangle-like prism, reflecting it once by the side face, and thereafter, fetching it as a parallel light. CONSTITUTION:A slender elliptical beam 4 is emitted from an active layer 2 in a joint surface 3 of a semiconductor laser 1. Even if this beam is reduced as it is, it is not suitable for recording and reproducing of a disk of a high density since it is not circular. The beam 4 is made parallel by a collimating lens 6, and thereafter, it is made incident to the base of an isosceles triangle-like prism 12. The beam 4 is totally reflected by the prism side face 12, and thereafter, refracted and emitted from other face, and becomes a parallel beam 13 whose width is narrower than that of the time of incidence. It is reduced by an objective lens 9 and irradiated to a disk 10. Since the long axis direction of the ellipse is narrowed, the section of the beam becomes like a true circle.
